- RAIL-BREAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 3&L735, dated June 29,18186. Application filed April 30, 1885. Serial No. 163,956. (No model.)Patented in England May 23, 1884, No. 8,151.

Our invention consists of a machine for dividing rails or rail ends intolongitudinal sections suitable for the manufacture of wire or for otheranalogous purposes.

The rails or rail ends to be split are first nicked along the desiredline of fracture and are then broken into longitudinal strips orsections by means of our improved machine, hereinafter described. I

In the accompanying drawings, Figure 1 is a side view, and Fig. 2 is anend view, of a machine embodying our invention. Fig. 3 is a detachedsectional view showing a flat-bottomed rail fired in position betweenthe breaker and anvil, to be broken into three longitudinal strips orsections. Fig. 4 is a similar sectional View illustrating a modificationof the breaker for dividing double-headed rails into three longitudinalstrips or sections; and Figs. 5 and 6 are similar sectional views, drawnto a larger scale, and showing the form of breaking apparatus adaptedfor splitting rails into two longitudinal strips or sections when theintended line of .division is taken along the web. Fig. 7 is a verticalsectional view, drawn to an enlarged scale, on the line 1 2, Fig. 1.

Our improved splitting or breaking device may be operated by anysuitable mechanism, but we prefer the construction illustrated in Figs.1, 2, and 7, in which A is the frame of the machine carrying on the beda longitudinal, anvil, b. Above this anvil is carried the breaker a,which in these figures is shown as of a construction for breakingflat-bottomed rails into three strips or sections, as illustrated alsoin the sectional View, Fig. 3. This breaker-bar a has two Wings, betweenwhich we prefer to ar- :range an adjustable holding-down bar, 0, for

securing the rail in position while undergoin the operation of breaking.

The breaker-bar a is in the present instance suspended from the shaft dthrough the medium of motion-bars e, securely fixed to the breaker-bar aand guided by plates f, secured to the frame. nected by bars 9 to strapsd, working on cams,

eccentrics, or their equivalents on the shaft d.

Rotary motion is imparted to the shaft d through the medium of aspur-wheel, h, carried by the shaft and geared into the pinion j,

keyed to the end of the driving-shaft k, the latter being provided withfast and loose pulleys k k", and a suitable fly-wheel, Z, so that when arapid rotary motion is imparted to the shaft 70, a slow rotary motion ofgreat power is imparted to the shaft d, and is converted into areciprocating motion to operate the breakerbar a.

WVhen a rail is laid upon the anvil b, and reciprocating motion isimparted, as described, to the breaker-bar a, the rail will be fracturedin a manner which will be readily understood. A similar result will beobtained by reversing the device and mounting the anvil on the movingpart of the machine while the breakerbar a is fixed, the rail in thiscase being brought up by the anvil to the fixed breaker to be split.

The preliminary nicking of the rails on the lines on which they are tobe split is preferably carried out in a separate machine; but themechanical parts requisite for each operation may be combined and workedfrom one source of motive power, or may form parts of one machine orapparatus. The rails or rail ends may be nicked on one or both sidesalong the intended lines or line of fracture to the usual depth,according as the rail is soft and tough or hard andbrittle.

In order to impart breaking-pressure from the shaft (2 to thereciprocating breaker-bar a only when required, or at the will of theattendant, the straps cl are slotted for the reception of chucks'm,intervening between the ends of the connecting-rods g and the straps d,so that when these chucks are withdrawn and a block or other deviceintroduced be- The motion-bars e are con-- tween the breaker-bar and theanvil b, the connecting-rods g and consequently the breaker-bar will notreceive reciprocating motion, although the shaft d will continue torotate.

A lifting connection of any suitable character may be made between theconnectingrod 9 and the straps d, and in the drawings I have shownscrew-studs or pins .9 fitted into the straps and adapted to verticalslots 3' in the connecting-rods, so that when the chucks m are returnedto the position shown in Fig. 7 the studs will be at the-upper ends ofthe slots, and the connecting-rods with the break er-bar will then becompelled to reciprocate with the straps d.

We prefer to connect the chucks m by links or arms m on a horizontalshaft, a, mounted in hearings in the fixed frame, and provided at oneend with a handle, 11., by operating which both chucks may besimultaneously inserted or withdrawn.

The holding-down bar a is carried by screws at each end of the frame,which screws, and consequently the bar 0, may be raised and lowered bymeans of a worn1-wheel, 1), into which gear worms on a transverse shaft,0, provided with a hand-wheel, 0, so that by turning this hand-wheel thebearingdown bar c may be raised or lowered.

By modifying the construction of the breakerbar, as shown in Fig. 4,double-headed rails may be broken into three longitudinal strips orsections, and in the modifications shownin Figs. 5 and 6 we have shown aconstruction for breaking the rails into two longitudinal sections, theholding-down bar in this case being dispensed with, while both anvil andbreaker-bar are modified somewhat in shape.

The herein-described apparatus forbreaking or dividing rails longitudinally, said ap paratus consisting ofa longitudinal anvil to receive the rail, and a correspondinglongitudinal breaker-bar to act upon the rail in the direction of itslength, and operating mech- ALFRED HILL.
